I have txs unconfirmed on blockchain.info for four weeks already. Three similar sized txs went through to Bittrex ok and the fourth just got stuck. Unconfirmed for that long probably means it hasnt even been added to the block or mempool? Word went round that smaller txs were being ignored because the fees were too low to make them mineable... Bittrex said the deposit went through but the actual amount was not added to my balance, and then Blockchain.info increased their min deposit and withdrawal amount, the rest is history! I was hoping 4 weeks was a record but apprently not. And now the same thing is happening on my GA wallet. Lots of little missing txs all add up (for someone). No word from support from either Blockchain.info, Coinify or Bittrex. Bitcoin confirmation fees have now become ridiculous IMO.
